For the determination of the life expectation of welded components by means of the structural stress approach comparatively simple finite element calculations are carried out to determine the relevant stresses.This fact is especially an advantage in practical applications.However,exact guidelines to build the finite element meshes have to be constituted.The examined design detail is especial critical in this respect.Therefore an alternative method to define the structure of the finite element meshes is described.The results yielded with the notch stress approach according to Radaj are regarded in comparison.Fatigue tests are used to check the calculated results.
